@ernjas I was going to ask if you also want a big family. (Just seen your answer)
I am an only child, I longed for a sibling until I had my own children and then some desire for a sibling was filled with my bio children.
My mum had me when she was 40 (I was an accident, she was told she could never have children)
She died when I was 23, that was the hardest thing ever, and I do feel it was made harder for me by the fact I had no siblings. I didn’t have a fucking clue what to do. Luckily my Dad & Mum’s sister helped me plan the funeral etc things like that.
There are pros and cons to being an only child.
It’s not all doom and gloom.
I recently accessed my mum’s medical records going back 50 years and was desperately hoping I’d find out she’d had a secret child before me (ok, reading my first paragraph I guess I would be over the moon still now if I found out somehow I had a brother or sister)
I have 3 children currently, and would definitely like more one day.
I’ve known I wanted lots of children since I was very young.
